KARAKTERISASI TUMBUHAN SUNGKAI (Peronema canescens Jack.) ASAL TIGA LOKASI DI PROVINSI BERDASARKAN METODE LC-MS

Abstract

Sungkai (Peronema canescens Jack.) belongs to the Lamiaceae family which has various active compounds function as antipyretic to antioxidant so it is widely used as medicine. Sungkai samples were taken from three locations in Riau Province, namely Kuantan Singingi, Pekanbaru and Siak. The purpose of this study was to characterize and determine the types of phytochemical compounds contained in sungkai plants and to differentiate sungkai from three locations in Riau Province using the LC-MS method. Sampling was carried out using a survey method. Samples were analyzed using the LC-MS system. Chromatogram was analyzed using the MassLynx program to obtain the compounds contained in the sample. Determination of compound names was based on the Chemspider database and compound groups based on PubChem. Grouping of the three origins of Sungkai was carried out using the NTSYSpc2.02 program. There were 296 metabolite compounds which were used for grouping sungkai from trhee regions. Results showed that ekstract leaf sungkai from three locations contain compounds belonging to the class of flavonoids, phenolics, alkaloids, amino acids, aromatic compounds, sesquiterpenoids, carboxylic acids, essential oils, medium-chain fatty acids and nucleic acid. Three sungkai from three locations were divided into two groups with similarity coefficient values ranging from 31% -48. Group I is from Kuantan Singingi and group II is from Pekanbaru and Siak. The metabolites found in this study are expected to be useful as basic data in the field of phytopharmaca and medicine.
